I am a biogeochemist who studies how nutrients such as carbon, oxygen, nitrogen and iron move through and interact with the environment. I am particularly interested in eastuaries and near-coastal environments, and you'll ofen find me in my waders, on a boat or walking along the beach. I have three major interests: Fermentation in coastal sands Nitrogen cycling in estuarine sediments Response of irrigating fauna to hypoxia Research area keywords BiogeochemistryEnvironmental GeochemistryWater QualityNitrogen CyclingEstuariesSandy sediments
